Geese

Canada Geese are regulated by the U.S. Fish and Wildlife Service under the guidelines set forth by the Migratory Bird Treaty Act of 1918 making it unlawful to kill, sell, hunt, disturb nests and eggs, or purchase and possess migratory birds unless permitted by the Secretary of the Interior.

One of the ways to reduce the number of visits from these "rats on wings" is to destroy the nests so they don't return the following year. This requires a permit from the DNR.

Geese like open areas like golf courses because they get nervous about predators when they can't see at least 10 meters around themselves. Most golf courses are mowed down low enough that the geese can see long distances.
